Abstract: A lamp assembly includes a lamp and a lamp package. The lamp includes a light-emitting portion with a flange at its base and electrically conducting leads extending from the base. The flange has a flat portion. The lamp package includes a cylindrical housing and a cylindrical cover. The housing has a base and a side wall, the base having holes for the electrical leads to pass therethrough, the bore in the housing being ssmaller than the flange of the lamp. A portion of the side wall of the housing has a flat key for engaging the flat portion of the flange. The cover has a side wall and an inwardly extending flange such that when the cover is slid over the lamp and the housing, the inwardly extending flange engages the outwardly extending flange of the lamp thereby holding it in place against the top of the housing and against the flat key of the housing.
